12893786 divided by 680 
We want to figure out the number of times 12893786 can be divided by 680.

Going ahead to step 1:
The number 680 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 680

Let's proceed to step 2:
680 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 680

Let's proceed to step 3:
680 can be fit into 128 0 times, resulting in a remainder of 128.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 128, we end up with 128.
Grab the next digit (9) from the dividend, add it to 128, then carry on: 1289 / 680

Advancing to step 4:
When dividing 1289 by 680, we get 1 with a remainder of 609.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 680 from 1289 leaves us with 609.
Append the next digit (3) from the dividend to 609 and continue with: 6093 / 680

Step 5:
If we divide 6093 by 680, we get 8 and a remainder of 653.
Put 8 as the next digit of the answer. 
Result so far: 18.0
The remainder is 653 after subtracting 5440 from 6093.
Bring next digit (7) of the dividend behind the 653 and repeat the process: 6537 / 680

Let's proceed to step 6:
680 can be fit into 6537 9 times, resulting in a remainder of 417.
Put 9 as the next digit of the answer. 
Result so far: 189.0
Deduct 6120 from 6537 and we're left with 417.
Bring next digit (8) of the dividend behind the 417 and repeat the process: 4178 / 680

Going ahead to step 7:
The number 680 fits into 4178 6 times, leaving a remainder of 98.
Write down 6 as next digit of the result. 
Result so far: 1896.0
If we subtract 4080 from 4178, we get 98.
Bring next digit (6) of the dividend behind the 98 and repeat the process: 986 / 680

On to step 8:
The number 680 fits into 986 1 times, leaving a remainder of 306.
Record the quotient 1 as the next digit in the result. 
Result so far: 18961.0
Subtract 680 from 986 to get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Let's proceed to step 9:
When dividing 3060 by 680, we get 4 with a remainder of 340.
Put 4 as the next digit of the answer. 
Result so far: 18961.4
Subtracting 2720 from 3060 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 10:
The number 680 fits into 3400 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 18961.45
Subtract 3400 from 3400 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
If we divide 0 by 680, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 18961.45
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 12:
The number 680 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 18961.45
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 18961.45 with a remainder of 0.0.
